Exactly, don't think for a moment that real feathers and a painted freeze dried head doesn't make a difference. I hunt big Easterns that see a lot of predators, human and otherwise, and they use their fantastic vision - often at great distances, to scrutinize other "turkeys" in the field. Subtle, natural movements, such as a twitch of a feather here and there can make the difference between them coming in for a closer look or not. The way that light falls on a real deke can make a heck of a difference as well. I have been hunting turkeys with a bow for decades, often without a blind, so details mean a LOT. The last 12 or so years I have limited my shots to mature longbeards only, making it even tougher. Knowing an area WELL, the habits and habitats of the turkeys that YOU HUNT, comes first of course.
